Ive noticed major problems with the mail lately - sending and receiving. our mail is hosted on murdock as well. when i asked about this issue, this was the response:
Our server murdock has been having numerous problems with email. We are
working on them to improve the performance of the machine but there is no
ETA at this time on when those will be complete. You can ignore the data
loss emails as they were not meant to go to you.
If there is anything else I can help you with just let me know.
not too promising. the big problem is that i just suggested moving a clients service to dreamhost because ive been using them with no issues for quite awhile. now that the move has been made they cannot send email or receive for periods of time throughout the day which is frustrating.
